National Mfg N221-614 Ss Eye Bolt 5/16x3-1/4 130LB 10-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N221-614 is a stainless steel eye bolt designed for lifting, rigging, and anchoring applications in trade and industrial environments. Each bolt measures 5/16 inches in diameter and 3-1/4 inches in length, and is supplied with a matching hex nut for secure installation. The stainless steel construction resists corrosion in wet, outdoor, and chemically active environments. Rated to hold up to 130 pounds, these eye bolts are suitable for light-duty rigging, cable routing, and tie-down anchor points. The package includes 10 individual eye bolts with hex nuts, making it a practical bulk option for contractors and service technicians stocking hardware.

These eye bolts are commonly used in HVAC, plumbing, electrical, and general construction applications where a fixed anchor or suspension point is needed. Typical uses include hanging conduit, supporting pipe runs, securing safety cables, and mounting equipment to wood framing or structural members. The stainless steel material makes them well suited for outdoor installations, rooftop mechanical equipment, and humid mechanical rooms where carbon steel hardware would corrode over time.

Compatibility

Installation Notes

Eye bolts should be installed by a qualified tradesperson following applicable structural and rigging guidelines. Always ensure the mounting substrate can support the intended load before installation. Thread the bolt fully into the material and tighten the hex nut snug against the surface to prevent rotation under load. Do not exceed the rated 130 pound capacity and account for dynamic or shock loads, which can reduce safe working load significantly.
